"Ah, that was amazing, Pet!" Harry groaned as Hermione pulled her mouth away from his softening cock.
They were in the Room of Requirement again, and his slave had just finished giving him another perfect blowjob. The Saturday had been brilliant so far. His slave had woken him up by pleasuring him with her mouth, and he had very much enjoyed giving the girl her morning spanking and fucking her afterwards.
After breakfast, they had retreated into the Room of Requirement, where he had immediately ordered her to blow him again. Now, she knelt at his feet, looking up at him with a scowl on her face. She was still fully dressed, however.
"You may swallow." he told the girl, who grimaced as she gulped down the load of cum in her mouth.
Harry then gave her a regretful smile. "Now, unfortunately, we don't have the time for a full training session this morning. I have to get better prepared for the tournament. But don't worry, I'll make it up to you later this afternoon."
Hermione gave Harry a pleading look but didn't answer. Truth be told, she was just glad for the respite, no matter how short it was.
"Well, I wanted to look into some cutting and explosion curses today." Harry told the girl. "You'll do the research, and I'll try to learn how to cast them. Alright?"
Hermione looked at him fearfully.
"You can really hurt people with those." she said anxiously. "Those curses can kill people. Several people at once, even!"
Harry nodded. "Yeah. That's kind of the point."
Hermione sighed. "I can't refuse when you order me. But maybe we could look into some defensive magic instead? Advanced shield charms, transfiguration or conjuration for blocking spells. We don't even have done basics like the summoning charm yet."
"Alright. You have a point." Harry conceded. "Let's compromise. I will learn the Bombarda explosion curse, and then I'll look into whatever shield charms you think are best."
"You could also try to learn silent casting." Hermione suggested, relieved to focus on an academic topic again. "It's sixth year material, but it'd be useful, and you should be powerful enough to do it."
"That sounds like a good idea." Harry said. "By the way, what I also meant to ask you: Do you know of something called Legelmancy?"
Hermione tilted her head. "You mean Legilimency?"
"Maybe. What is it?"
"Legilimency and Occlumency are a form of magic called the Mind Arts." Hermione explained. "Occlumency is the art of organising your mind and protecting it from invasion, while Legilimency is the offensive counterpart. Mind reading, if you will. It can be done passively, which usually requires eye contact, or actively with a spell, then it is more powerful."
"Huh." Harry muttered.
"Why do you ask?" Hermione wondered.
"Dumbledore said he used it on me." Harry told her.
Hermione gave him a sceptical look. "He wouldn't. It's illegal to do that without consent."
"I heard him admit to it to Snape." Harry said.
Hermione frowned. "Well, if he really did, he would have had a good reason, with you breaking the rules, and I guess as Supreme Mugwump he kind of has the authority--"
"I didn't--" Harry started, but then shook his head in exasperation. He was getting annoyed of her blind trust of authority again, but she had been and would be very helpful, so he decided to let it slide this one time.
"It doesn't matter." Harry said. "Can we learn these things?"
"It was only referenced in the books I read." Hermione said. "Books with actual instructions would be in the restricted section of the library."
"Or here in the room." Harry mused. He concentrated and wished for books on the Mind Arts. Seconds later, two tomes materialised on the table.
"That's amazing!" Hermione exclaimed, gushing over the books. With the room capable of providing books on any given topic, everything else was instantly forgotten.
"Let's look at those first. That's even more important than the other spells." Harry decided.
He and Hermione took one book each and began to read.

Harry was in an excellent mood when they went down for lunch that day. Naturally, they hadn't gotten very far on the Mind Arts within a few hours, but he was hopeful that he would be able to block at least passive legilimency within a few weeks of meditation exercises.
Hermione had been a great help, and Harry thought that he had to do something nice for her later. Her slight attitude problems persisted, but she had made up for it by being a brilliant researcher and instructor. He really had to give her a reward that she would enjoy fully.
When they entered the Great Hall, McGonagall approached him. "Mr Potter, you are wanted in the headmaster's office after the meal." she informed him.
That had to be about his missed detention with Snape. Harry had expected this and wanted to use the opportunity to cause another scene.
When he was done with his meal, he got up and approached the head table.
"What do you want to speak to me about, headmaster?" he asked with an indifferent voice, though he was careful to avoid looking into Dumbledore's eyes.
"We will speak about this in my office, my boy. Please return to your table." Dumbledore said.
"I already have plans for after lunch." He glanced at Hermione and winked at her. "But we can talk now."
Dumbledore sighed. "Very well. Professor Snape informed me that you didn't show up for your detention with him last evening. I have to say I'm very disappointed with you. You will serve detentions with Mr Filch for the full next week instead."
"No." Harry replied simply.
"Eh--excuse me, my boy?" Dumbledore sputtered.
"You are excused. Anything else, Albus, my old chap?" Harry asked with a grin.
He enjoyed the increasing annoyance on Dumbledore's face.
"Harry, you will address me by my proper title, and those detentions are not up for debate." Dumbledore demanded.
Harry raised his eyebrows at the headmaster. "Albus, I will show you the same respect you show me. And I won't serve any detentions."
"I will have you expelled for this!" Snape shouted irately.
"Professor Snape is right. I you continue to tread this path, Harry, I fear I will have to expel you." the headmaster told Harry with a grave voice.
"Go ahead, I would be glad to finally leave this death trap of a school." Harry said mockingly. "And southern France is said to be a beautiful place all year round..."
Dumbledore paled.
"Now, my boy, I'm sure that won't be necessary." he said hastily. "I'm prepared to let the detentions go this time, if you promise to change your attitude."
"I'll change my attitude as soon as Snivellus changes his." Harry said and turned around.
He ignored the calls of "Harry!", "Potter!", and "Mr Potter!" from Dumbledore, Snape, and McGonagall and strode out of the Great Hall.
When he passed the Gryffindor table he took Hermione's hand and pulled her up, dragging her out of the hall with him.
Hermione scowled at him while they walked away from the hall through empty corridors.
"You are making things only more difficult for yourself by being so disrespectful to the headmaster and Professor Snape." she complained.
Harry whirled around and glared at the girl. He was astonished by her tone. Had she learnt nothing from the day before? Apparently not. It seemed that she just couldn't help herself. Clearly, her bossiness was far too ingrained in her than to be corrected with a single training session.
Hermione paled ghostly white when she realised what she had said.
"I'm sorry!" she blurted out. "I didn't mean it! Please! I didn't mean it!"
"I can't believe how stupid you are!" Harry hissed.
He shook his head with disappointment. The girl had been so good this morning! He had been thinking about rewarding her! He saw how wrong he had been to ignore her attitude problem. He needed to remedy this immediately.
"I see that you haven't learnt anything from yesterday." he said coldly. "That's what I get for being too soft with you."
"Please! No! Please, Master! I didn't mean it!" Hermione wailed in panic.
"Shut up!" Harry growled and pulled her into the closest unused classroom.
He closed the door behind them and pushed Hermione against the teacher's desk, bending her forward. She only gave a weak squeak in protest.
With one hand, he pushed up his slave's skirt, while he freed his already stiff cock with his other hand.
He aligned his shaft with her back-entrance and pressed his tip against her puckered hole.
"Ahh! No! Please, not there! Not again! Please! I'm still sore from yesterday! Please, Master, you can fuck my pussy, I'll be good, but not--AAHH!" Hermione's pleading ended with a cry of pain as Harry rammed his cock fully into her arse.
He continued to pound into her for several minutes, and her cries of pain slowly gave way to weaker moans.
Harry cupped his slave's pussy with one hand and entered two fingers into her increasingly moist vagina. But this quick session was not about Hermione's pleasure, but about him releasing some anger. He just enjoyed making her squirm a bit more.
Soon, Harry shuddered, and with a yell he filled his slave's arse with his cum. He pulled out, spun Hermione around and forced her down on her knees in front of him.
"You know what to do." Harry said while Hermione looked at his filthy cock in disgust. With a quiet sob, she grabbed his cock and took it in her mouth to clean it, while she felt his cum ooze out of her sore anus.
"Well done, slut!" Harry said with a content groan when she released him. "Did you enjoy yourself?"
Hermione just looked at him pleadingly with teary eyes, still scowling from the disgusting taste in her mouth. She shook her head slightly.
Harry's gaze turned cold. "Because this is what happens when you're a bossy, authority worshipping nag. For speaking out of line on issues you know nothing about, we will repeat this during every study break this weekend."
Hermione's eyes widened in fear.
"Yes, that's right." Harry said with a cruel smirk. "You'll be a good anal whore once we're done."
"Please!" Hermione whispered desperately. "Don't do this!"
"Nothing of this now, you only have yourself to blame for this." Harry said dismissively. "Get up! We have to go to the Room of Requirement."
